Smart has never been so simple
With the Nucleus® Kanso® 2 Sound Processor, smart has never been so simple.
Designed for active lifestyles, the Kanso 2 Sound Processor combines off-the-ear comfort with our latest connectivity features and proven hearing performance technology1-4, giving the freedom to hear wherever life takes them.
Building on the award-winning all-in-one design of the Kanso Sound Processor5, the Kanso 2 Sound Processor introduces direct streaming* and use of the Nucleus Smart App** from compatible Apple or Android™ devices. It also features a built-in rechargeable battery and improved dust and water resistance+ for added peace of mind.
The world’s smallest and lightest rechargeable off-the-ear cochlear implant sound processor6, Kanso 2 is designed to be so discreet and so comfortable they’ll barely notice they’re wearing it.
Colour options to match your personal style
The Kanso 2 Sound Processor is available in five different colours, so you can choose the one that best suits you.
Focus on what's important
"I absolutely love the fact that the [Kanso 2 Sound] Processor is off the ear ... because it's very sleek, it's a very nice design, and I can wear my glasses ... without so much being on my ear."
- Solidea, Cochlear™ Nucleus® System recipient
Filter out background noise
Dual microphones work together to filter out background noise and provide better hearing performance in noise than a single microphone.2
Hear well in different environments
Capture every moment. Whether in a quiet room or outside on a windy day, the device will automatically adjust using SmartSound® iQ with SCAN technology.
Bring sound closer – no strings attached
Cochlear™ True Wireless™ technology helps free an adult or child (and their hands) to focus less on hearing and more on what's important for them.
Enjoy face-to-face conversations
Activate ForwardFocus~ in the Nucleus Smart App to decrease distracting noise coming from behind, so that they can better hear the person in front of them.4
Peace of mind for parents
"She can be whatever she wants to be, and find who it is that she is going to become. Phoebe does really well at school. She has awesome teachers. She's taken off."
- Cynthia S, mother of Phoebe, Cochlear™ Nucleus® System recipient, USA
